|Nov-18-15|| ||roentgenium: I have to admit defeat on this one, erroneously believing 27. Qh6+ would eventually lead to recapture of the f8 Knight, without seeing that it was defended both by Queen and Rook, and that the Black King can only self-block one of those at a time. |
With the aid of an analysis board, I found <agb2002>'s solution, so 27. Qh6+ is indeed a winning line - but I doubt I could evaluate all of the variations in a real game.
|Nov-18-15|| ||saturn2: <penguincw (assuming the queen doesn't take on f8).> After 26 Rxf8 <..26 Qxf8> was NOT the reason I did not like this variation. After 27 Qh7+ black has to give his queen for the bishop. The reason I did not like this variation was ...26 Rxf8, because after 27 Qh7+ Ke8 28 Bxg6 black can escape to ...28 Kd8. And it was unclear to me whether white can push to g6 pawn successfully to queening.|
However I liked 26 Bxg6.
|Nov-18-15|| ||morfishine: After <26.Bxg6+> Black's position transitions from teetering to collapsing|
|Nov-18-15|| ||stacase: Hmmm, say check with the Rook or the Queen? Oh! the Bishop can say check too. Yeah, that works.
|Nov-18-15|| ||CHESSTTCAMPS: White is down a knight for a pawn, but has a winning attack against the exposed king, with black's bad bishop and disconnected rooks of little value in defense. Only black's knight is a pesky defender (and the queen could have a role if there's a misplay), but white can muscle through with |
26.Bxg6+! forcing mate shortly:
A) 26... Nxg6 27.Qh7#
B) 26... Kg7 27.Qh6#
C) 26... Ke7 27.Rh7+ Nxh7 28.Qxh7+ Kf8 29.Qf7#
D) 26... Kxg6 27.Qh5+ Kg7 (Kf5 28.Qf7#) 28.g6!! (Qh6+ Kf7 drives the king to safety) Qa3/c3+ 29.Kg4 Nxg6 30.Qh7#
D.1 29... Nh7 30.Qxh7#
D.2 29... other (except a queen spite check) 30.Qh6#
Time for review...
|Nov-18-15|| ||thegoodanarchist: <Penguincw: Wednesdays. The middle of the work week, and also the day where <cg> puzzles start getting harder (if they haven't already).|
Yeah, I missed this puzzle, as my first move was 26.Rxf8+, did not consider any other variations.>
Don't feel badly, that's exactly what happened to me.
It really irks me that I didn't consider the Bishop capture/check, since ...Nxg6 allows immediate mate. I am getting rusty since I stopped playing...
|Nov-18-15|| ||CHESSTTCAMPS: <agb2002: <devere>'s solution is far simpler...> For those accustomed to giving priority to forcing alternatives (usually the most fruitful approach), the technique of cutting off the escape route is sometimes hard to find. I only found 28.g6 in line D after finding frustration with the forcing alternatives.|
|Nov-18-15|| ||kubbybulin: Don't you hate it when you have your analysis written out in outline form, and you go to post and the post directly before yours is identical (even the ordering)? I omitted one small detail though (D. 27. ...Kf5 28. Qf7#). You must play correspondence CHESSTTCAMPS. Well done.|
|Nov-18-15|| ||whiteshark: <26.Bxg6+!!> That's it!|
|Nov-18-15|| ||kubbybulin: Btw today's puzzle was exponentially more difficult than yesterday's. I am scared of Thursday.|
|Nov-18-15|| ||mel gibson: So easy|
|Nov-18-15|| ||dfcx: White can check with Rh7, Qh7, Rxf8 and Bxg6. The first two fails due to the knight's guard. Rxf8 fails to Qxf8. That leaves |
A. 26...Kxg6 27.Qh6+ Kf7 28.Qf6+ Ke8 29.g6 wins
B. 26...Ke7 27.Rh7+ Nxh7 28. Qxh7+ Kf8 29.Qf7#
C. 26...Nxg6 27.Qh7#
Reading the other's post, my line A is not good, 27.Qh5+ is better
|Nov-18-15|| ||dark.horse: <stst> "CG should have more detailed analyses..."|
That job is on the kibitzers.
|Nov-18-15|| ||varishnakov: I think this is a case where CG misevaluated the difficulty of the puzzle due to the game continuation being simpler.|
|Nov-18-15|| ||paulalbert: Like some others instinctively looked at Rxf8ch first, but could not make it work, so looked at Bxg6ch and was able to work out the variations to make it work.|
|Nov-18-15|| ||BOSTER: <stst: CG should have more detailed analyses>.
You don't know about CG analysis anything.|
|Nov-18-15|| ||kevin86: I went the way...of Rf8+ ouch! My other move Bxg6+ the king must take as the knight is pinned!|
|Nov-18-15|| ||YouRang: Yep - 26.Bxg6+ easy since black can't recapture without being quickly mated, so black needs 26...Ke7. But then, with R, B, Q and Pe5 all ganging up on weakly defended kingside, it's got to be over soon.|
So, you can play 26.Bxg6 even before you calculate mate, and once you play it, mate isn't hard to find.
|Nov-18-15|| ||rozzatu: <stst>
A more subtle journey (B):
31.Qxe6 is not mate.
|Nov-18-15|| ||CHESSTTCAMPS: <kubbybulin:> I did play correspondence chess, with some success, more than 30 years ago. (Geez, that makes me sound old or something.) Sometimes the ordering of my solutions is a bit random, but today I was intentionally going from simplest to longest, so it's not too surprising that you came out similarly.|
|Nov-18-15|| ||gawain: I missed this one. Among other things, I did not notice that after 26 Rxf8+ Black can retake with the queen.|
|Nov-18-15|| ||ruzon: <stst: line (B): 31. Qxe6+>, Qe7 and then what?|
|Nov-18-15|| ||JeffH1165: I immediately saw Rh7+ as well. That line seems to work out just fine for White . . .|
|Nov-18-15|| ||Est2002: Qh6 looks ok to me.|
|Nov-18-15|| ||jheiner: <JeffH1165> I thought Rh7+ would suffice, forcing the capture with Nxh7 and invasion by the Q and B. However upon analysis found that Black can simply repeat the position with Kg8.|
OTB it would be pretty simple to adjust and find Bxg6 I would think.
